The PMS 110, 130 and the WCS 150 can be set up by an off-track wager service provider in some embodiments, the computer systems 111 and 131 can communicate with the WCS 150 through an intranet managed by the off-track wager service provider.

A plurality of computer devices 160, 170 can be connected to the computer network 105 and communicate with PMS 110, 130 and the WCS 150. The computer devices 160 and 170 can include personal computers, portable digital assistance (PDA) devices such as Palm™ and Blackberry™, cellular phones, digital image capture devices equipped with communication devices, portable, music players such as IPOD™ and Zunc™, and game devices such as Microsoft XBOX, SONY PlayStation OR PS2, and/or Nintendo 64, GameCube, or GameBoy.

The PMS 110 and 130 can each be installed at or near a race track. For example, various components of PMS 110 can be installed at or near a race track 200. A plurality of animals 212, 213 such as horses and greyhounds can participate in a race on the race track 200. Each racing animal 212, 213 can carry the portable device 112 or 113. A coordinate system including an origin, an x-axis, and a y-axis can be defined in the race track 200 for easily describing relative locations of the racing animals 212, 213 in the race track 200 and the relative positions between the racing animals 212, 213. The relative positions of the racing animals can also be based on distances along the race track 200. For example, distance from the start position “T₀” can be measured along the race track to indicate the distance a racing animal has run.

The racing animals' (or vehicles') positions can be measured by different arrangements. In some embodiments, referring to FIG. 3, the portable device 112 can include a GPS communication device that can receive electronic signals from a plurality of satellites 231-233 (for example, the location of a racing animal may be accurately determined by signals from four or more satellite or by signals transmitted to four or more satellite). The electronic signals received from the different satellites 231-233 can be used to calculate the absolute locations (e.g. in longitudes and latitudes) of the racing animal 212 by a computer processor 320. The computer processor 320 can optionally calculate the relative location of the racing animal 212 in the race track 200. A wireless transmitter 330 can send the absolute location and/or the relative location of the racing animal 212 to one or more of the wireless receivers 114-119. The positions for the racing animals 212, 213 can be measured at pre-defined time intervals. The computer system 111 can receive the position (and optionally time associated with the position measurement) from the wireless receivers 114-119. The computer system 111 can calculate the relative locations of the racing animals 212, 213 in the race track 200 using the absolute locations of the racing animals 212, 213.

In some embodiments, the GPS communication device 310 can transmit electronic signals to one or more satellites 231-233. The electronic signals can carry position information about the racing animal 212. The one or more satellites 231-233 can send the positions of the racing animals to the computer system 111 or the WCS 150. The wireless transmitter 330 and the wireless receivers 114-119 may not be required in this arrangement.

In some embodiments, the racing animals' locations can be measured without a GPS system (including the satellites 231-233 and the GPS communication device 310). The wireless signals transmitted by the portable devices 112, 113 can be measured by the wireless receivers 114-119 for determining the positions of the racing animals 212, 213. In some embodiments, the relative intensities of the wireless signals transmitted by a portable device 112 can be used to calculate the location of the racing animal 212 at the time of transmission. In one arrangement, the relationship between the different race-track locations of the portable device 112 and the relative intensities received by the different wireless receivers 114-119 can be calibrated prior to a real race. The ratios of the intensities can be used to uniquely determine the location of the portable device 112 (and thus the racing animal 212) on the race track 200.

In some embodiments, the racing animals' locations can be measured by short-range position measure devices such as RFID readers or optical interception devices. The portable device carried by a racing animal can include a RFID sensor having a unique identification. A plurality of RFID readers can be positioned along the race track to detect the specific radio frequency (RF) signals emitted by the RFID sensor. The RFID sensor can include a power supply or being powered by inductive RF signals from the RFID readers. An example of an optical interception device can include a laser beam and a photo sensor installed by the race track. The laser beams is set up to illuminate across the track into the photo sensor. An interruption in the laser signal by a racing animal can be used to determine the location of the racing animal.

The off track wager system 100 can provide wagering services to many players. The players can register and open accounts at the off-track wager system 100 through the computer network 105. A player can access their accounts using a user name and a password. The players can also have store money in his account for automatic withdrawal of wager fees. The user account information and the wager information, can be stored in the WCS 150.

Referring to FIG. 1-4, the operations of the off-track wager system 100 can include following steps. A race can be hosted at a racetrack 200. The racing animals 212, 213 positions can be measured by position measurement system (PMS) 110 (step 410). The racing animals' relative locations in the race track 200 can be calculated using their measured absolute locations by the computer system 111 or the computer processor 320 (step 420).

The (relative) locations of the racing animals 212, 213 running in the race are sent to a remote computer device 160 (step 430) and received by the communication module 610 (FIG. 6). The relative positions of the racing animals during the race are instantaneously displayed on the display 640 of the remote computer device 160 (step 440). The racing animals' relative locations can also be sent to and stored at the WCS 150. In some embodiments, the racing animals' relative locations in the race track 200 can also be calculated in WCS 150 or by the computer processor 620 in the remote computer device 160.

A player can log-in to the off-track wager system 100 using the input device 630 on the remote computer device 160. The player can enter a wager prior to a race using the remote computer device 160 (step 450). The player can monitor the performance of the racing animals 212, 213 during a race. The player can enter a wager during the race using an input device 630 in accordance with the performance of the racing animals 212, 213 during the race. Information about the wager can be transmitted to the WCS 150 (step 460) and stored in association with the player's account. The winning odds for the pari-mutuel betting can be continuously computed by the WCS 150 (step 470). The updated winning odds and other race related information can be received by the computer devices 160, 170. After the race results are known after the race, if the player wins, the winning amount is computed by the WCS and stored in the player's account at the off-track wager system 100.

A WCS 150, referring to FIG. 5, can include an account management subsystem 510, a pre-race status subsystem 520, an in-running status subsystem 530, an odds computation system 540, a betting subsystem 550, and a post-race subsystem 560. The account management subsystem 510 can store information about users of the off-track wager system 100. The user information can include user identification, password, name and address, account, balance, current active bets, betting history, performance analysis, money transfer information (e.g. credit card, bank account information, and other electronic payment method such as Paypal), bonus point management, and payout calculation. The user account can be registered by users using the computer devices 160, 170 through the computer network 105. The user information can also be entered and managed by the users and updated by the account management subsystem 510.

Before each race at a race track 200, a user can receive pre-race information about the race from the pre-race status subsystem 520. The pre-race information can include race schedules, participating animals in the race, pre-game odds, the sizes of each betting pool, race status, track status, track assignment, profiles of the racing animals, jockey profile including historic performance, expert's picks, weather information at the nice track, and scratch update. The pre-race information can be pre-stored in the WCS 150 (e.g. historic data), or received from the race track 200 (weather, scratch, and track information) or other race information agencies. The pre-race information can be sent to the pre-race status subsystem 520 through the computer network 105 or through other communication methods. The pre-race status information can also include updated odds for each type of bet for a given race. The odds information can be received from external sources or from the odds computation system 540.

The players can receive pre-race information using the computer devices 160, 170 and enter bets on the racing animals. The bets are received by the betting subsystem 550 from the computer devices 160, 170. The betting subsystem 550 can verify the validity of the bets, and decides to accept or reject the bets. The balance in the user's account may be checked to ensure sufficient fund is available for the bets. Fees for the bets can be withdrawn. A confirmation message may be sent from the WCS 150 to the computer devices 160 or 170 to inform the players about the successful entries or rejections of the bets.

The official results after each race can be received by a post-race subsystem 560 from the race tracks 200 or other agencies. The outcome for each bet is determined. The winning amount, is calculated for the winning bets. The appropriate fund is transferred into the user accounts associated with the winning bets.

The players can also receive in-running information from the in-running status subsystem 530 during a race. The in-running status can include the positions and relative order of the racing animals 212, 213 and real time video or audio information from the race track 200. As discussed below, the in-running information can be displayed on the computer devices 160 or 170 in image, text, or multi-media presentations/animations. The in-running status can be received from the race track 200, the PMS 110 and 130 associated with the race tracks, and other systems that may capture live race information. For example, the in-running information can include video signals captured by an electronic Video or still-image camera. The in-running status subsystem 530 can also receive the positional information of the racing animals from the satellites 231-233 if that may determine the locations of the racing animals 212-213 using the signals transmitted from the GPS communication device 310. The in-running status subsystem 530 can also calculate the relative positions of orders of the racing animals 212, 213 in the race track 200 using the location information measured by the PMS 110 and 130, or received from the satellites 231-233.

In some embodiments, the off-track wager system 100 can facilitate players to make bets during a race (i.e. in running). The players can send bets during a race to the betting subsystem 550 using the computer devices 160 or 170. The betting subsystem 550 can verify the validity of the bets, and decides to accept or reject the bets similar to the bets entered before, tire race. Due to the shorter time available, the betting subsystem 550 may pre-qualify certain players that can make bets during a race. For example, the betting subsystem 550 may only allow players having good betting and credit records to make bets during a race. The betting subsystem 550 can also require a minimum fund to be available in the player's user account and specific in-running conditions to be agreed upon.

The in-running betting information can also include the winning odds and the pool sizes for the pari-mutuel bets. During the race, the odd computation subsystem 540 can continually calculate the winning odds from different bets using information received from the track 200. PMS 110-130, and other sources. The players can receive the winning odds and the pool sizes during the race using the computer devices 160 or 170, which can help the players make bets during the race.

In some embodiments, the in-running bets can be arranged in different time segments during a race. For example, referring to FIG. 2, a race may start at position “T₀” and finish at position “T₄”. The race can be divided into four segments “T₀ to T₁”, “T₁ to T₂”, “T₂ to T₃”, and “T₃ to T₄”. The in-running bets may be accepted during some or all the tour segments. For example, the in-running bets may be entered during the “T₁ to T₂” and “T₂ to T₃”, segments, that is, after the racing animals have demonstrated their performances but before they are too close to the finish line. The bets can be entered separately for the “T₁ to T₂” and “T₂ to T₃” segments. The odds computation system 540 can calculate the winning odds for each segment in accordance with the number of bets for each racing animal during that segment. The odds in a segment can be calculated using pari-mutuel principle based on the money betted in this segment only. The odds of different segments can be calculated independently from each other. The odds of different segments can also be calculated based on the bets in several segments.

Furthermore, the odds in a segment can be calculated before the segment is closed. Alternatively, the odds for a segment can be calculated dynamically as the bets and the money are received and updated as the race progresses during the segment. The winning odds, the total size of the bets for each segment can be sent to the computer devices 160 or 170. The winning odds before a race and the winning odds for one or more segments during a race can be displayed on the computer devices 160 or 170. Moreover, the wining odds for the current in-running segment during a race can be displayed on the computer devices 160 or 170 (shown in FIGS. 7A and 7B below).

In some embodiments, the segmentations can also be based on the time. For example, the average run time for a race can be divided into rive segments wherein in running bets can be entered in the second, the third and the fourth segments. Other embodiments can include all or any subsets of the segments “T₀ to T₁”, “T₁ to T₂”, “T₂ to T₃”, and “T₃ to T₄”. A race may include a portion, one or more rounds around a race track. More or fewer segments can be defined for a race.

In some embodiments, the off-track wager system 100 can facilitate a social network among the players. For example, the players can post messages on a bulletin board and chat in chat rooms to exchange information and opinions about racing animals, jockeys, and so on. The WCS 150 can allow a group of players to create an account to make bets on racing animals before or during races.

Referring to FIG. 6, the computer device 160 can include a communication module 610, a computer processor 620, an input device 630, a display device 640, and a memory module 650.

The symbol 712, 713 can also include an image or animation resembling the racing animal (e.g. a horse or a greyhound), an avatar, an icon, a dot, a circle, a rectangle, a polygon, a star, a symbol such as “+” or “x”.

The computer processor 620 can produce a digital image including the symbol representing the racing animal in the representation of the racetrack. The position of the symbol in the representation is determined by the positions of the racing animal. The digital image can be displayed on the display device 640. A series of such images can be produced by the computer processor 620 which can simulate the movement of the racing animal in the race track during a race. The player of the computer device 160 can easily determine the relative positions and speeds of the racing animals as the race progresses and can make in-running bets accordingly using the input device 630.

A larger view 720 of the relative positions of the racing animals can also be displayed to more clearly show the relative positions of the racing animals. For example, in a race participated by eight horses, the positions of the eight horses in running can be represented by arrow signs labeled by the horses' numbers in the larger view 720. For example, the eight horses are sequenced in the order of 6, 4, 2, 1, 5, 8, 3, and 7 at the moment of the race, shown in FIG. 7A. Horse number 6 is leading the group at this particular moment. The relative positions and timing of the horses can be displayed in a table 730. The row “P” lists the updated sequence of the horses in running. The row “H” indicates the horses at each position The row “T” can display the times for the horses to catch up with the leading horse (horse number 6 at the moment). The updated winning odds for the horses can be displayed in table 740. The winning odds for horses 1-8 can be categorized for win, place and show. The winning odds can be calculated from one or more previous segments or dynamically calculated using the bets placed in the current segment. Moreover, the information listed in tables 730 and 740 can include updated in-running information and post race information including the official results.

The display device 640 can also display the relative positions or the ranking order of the racing animals during a race in accordance with the location in the racing animal in the race track. For example, in a horse race, a table in the user interface 700 may include rows of information each for a racing horse. Different columns can include tire names of the horse and the jockeys, the track numbers for the horses, tire current running sequence for the racing horses, as well as the current number of bets and winning odds for each bet on the horses. The user interface 700 can also include features for accepting bets for different horses and different wagering configurations. Referring to FIG. 7B, tables 751 and 753 can include a plurality of cells for win, place and show for each of the racing horses (numbers 1 through 8). Different betting amount can be listed in the same table or different tables 751 and 753. A user can select betting configurations such as win for horse number 4 and place for horse number 6 at $2 betting value by clicking the corresponding cells in table 751. Similarly, the user can also select betting configurations such as place for horse number 2 and win for horse number 7 at $6 betting value by clicking the corresponding cells in table 751. Other betting amounts can also be included in the user interface 700. The user can click a button 760 to verify the betting(s) he or she placed. The user can click a button 770 to submit the bets. A plurality of bets can therefore submitted by clicking a button.

It is understood that user interface for the computer device 100 or 170 can take different forms. For example, the betting on a horse can begin by a user using a mouse to click on the arrow sign labeled by the corresponding horse in the larger view 720. A pull-down menu can occur next to the horse to allow the user to choose a betting method such as “win”, “place” or show” After the user clicks on one of these betting methods, a pull-down menu can give the user selections on the betting amount such as $2, $4, $6 . . . , and so on.

Embodiments of the systems and methods disclosed herein include one or more of a number of advantages. One advantage of the in-running betting is that, the winning odds may fluctuate as a function of the performance of the racing animals during the race. The dynamics and added uncertainty can make the in-running betting more exciting than pre-race betting. Another advantage of the in-running betting is that a player can make bets using a combination of pre-race betting and in-running betting. The in-running betting can thus make wagering more entertaining and may attract more players to participate in off-track wagering.
